This invention relates to radiators and improvements therein and is illustrated herein in connection With a radiator of the same general type as that disclosed in United States Letters Patent No. 1,681,173 granted August 21, 1928, upon application of E. V. Daily and assig'ned to the assgnee of the instant application.

Radiators of the type described in the aforesaid patent comprise, generally speaking, a plurality of aligned sections which are connected with one another to form a Water circulatin; Chamber in the upper' part of the radiator proper and a combustion Chamber in the lower part of the radiator. The structure is self-contained in the Sense that it is not connected by pipes or otherwise With a central heating' system hut employs a burner Within its combustion Chamber for heatine; "'i the Water and need only be connected with a suitable source of fuel sup] :ly to be operative. It customary in such radiators to insert a fuel burner extending lengthwise of the combustion chaniber and to form in the bottom of the combustion' Chamber an openino' for the admission of air to support the oombustion.

rlhe patent mentioned above is directedv to the important feature of disposing a bafiie above the air inlet opening to`` prevent refuse from the burner falline` through the opening' and reachin; the floor of the rooin in which the radiator' is placed. The present inveny, tion has for its object the improvement of the i battle arranefenientdisclosed in said patent.

In accordance with the present invention, a plurality of air inlet openines are formed Within the bottoni of the radiator and battles :i are disnosed above the opening's in such a manncr as to divide the incominn' air into a plurality of streams one of which serves as a primary air stream and the other as a secondary air stream.

Other objects and features of the invention Will become ailiparent from a reading of the following specification in the light of the appended drawings, in which Figure 1 is a somewhat diag nmmatic view, shown partly in section, of a radiator cornprisin-g a plurality of Sections embodying the invention.

Figure 2 is a view in side elevation of a sngle section equipped inv accordance With the present nvention. Y

F igure 3 is a view in section taken along the line 3-3 of Figure 2,1and

Figure 4; is a bottom plan View of the .section shown in Figure 2.

Referring to the drawings, there is shown in Figure 1 a radiator comprfsing a plurality of Sections 27 4, 6, 8 and 10 of the type shown in Figure 2. Each of these Sections comprises, asd-isclosed in Figure 2, a water chamber 12 located. within the upper portion of the section a-nd a combustion Chamber 111 formed within the lower portion thereof. The Sections are joined together by means of n`=pples 16 and projecting laterally from the sides of the Water Chamber and by means of laterally extending side walls 18' projectint;` from the combustion chambers 14. Thus, when a radiator is assembled, the Water chambers of the adjacent Sections are in communication With one another by means of the nipples 16 and 20 and the comb'ustion chambers of the several Sections are aligned With one another andunited to form a single large Chamber extending throughout the length of the radiator in the bottom portion thereof. i

During the use of the radiator an elongated burner 21 is inserted lengthwise of the combustion Chamber 14; of the radiator and is supplied With a suitable quality and quantity of fuel for heating the Water Within the water Chamber. To insure proper combustion it is necessary to supply air to the burner and in accordance With the present invontion such air is supplied in the following` manner.

The comhustion Chamber 14 formed in the bottom of each radiator section comprises a front Wall 22, a rear Wall 241 and a bottom Wall 26. The bottom wall is provided With a plurality of air inlet openings 28 and 30 disposed upon opposite sides of the center of the bottoin Wall and in operation air flows through the openings 28 and 30 and mingles 'with the fuel issuing' from the burner to assure proper combustion.

As disclosed in Figures 2 and 3 baflles 82 and 34 are disposed above the air inlet openings 28 and 30 and serve to prevent refuse from the burner escaping through the openings. As shown, the bafiies comprise horizontally extending portions and VVertically eX- tending portions 36 and 88, said portions being spaced respectively from the bottom wall and the front and rear walls of the combustion chamber, and having their inner ends spaced from one another to provide a central opening 40 between the battles.

In operation, air flowing through the openings 28 and 30 strikes the bafiies 82 and 3a and is divided into a plurality of streams, one of which fiows through the central opening 40 and thence immediately to the burner,.whereas, the remaining streams fiow through the passageways defined by the front and rear Walls 22 and 24 of the combustion chamber and the vertically extending portions 36 and 38 of the baflies. As the remaining air streams reach the top of the vertically extending portions of the baffies they flow inwardly above the burner and further support the combustion of the fuel.

In the sense that the air stream flowing through the opening 40 is the first toreach the burner it may be considered for purposes of description the primary air stream and the remaining streams which flow upwardly through the Vertical passageways and are the last to be added to the combustible mixture may be considered as secondary air streams. The feature of dividing the incoming air into primary and secondary air streams is desirable and increases the efficiency of the radiator.

Although as illustrated herein each section is formed With openings confined within the bottom Wall of the combustion chamber, it is to be appreciated that elongatedopenings extending completely through the bottom wall and disposed lengthwise of the radiator might also be provided. In other Words, as herein disclosed, there is provided a series of air openings extending lengthwise of the bottom wall of the radiator but the openings in each series might within the contemplation of the applicant be changed into one long-opening Without departing in any Wise from the spirit of the invention herein. It is likewise to be understood that other modifications and rearrangements of the parts may be made Without departing from the true scope of the invention as described herein and as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
